the day. Fully functional DRL are
required on all vehicles first sold in
Canada.
The dedicated DRL will come on when
all of the following conditions are met:
.The ignition is on.
.The exterior lamp control is
in AUTO.
.The light sensor determines it is
daytime.
.The parking brake is released or the
vehicle is not in P (Park).
When the DRL are on, the taillamps,

Ending Cruise Control
There are four ways to end cruise
control:
.Step lightly on the brake pedal.
.Press*.
.Shift the transmission to
N (Neutral).
.PressJ.
Erasing Speed Memory
The cruise control set speed is erased
from memory if
Jis pressed or if the
ignition is turned off.
Adaptive Cruise Control
(Advanced)
If equipped with Adaptive Cruise
Control (ACC), it allows the driver to
select the cruise control set speed and
following gap. Read this entire section
before using this system. The
following gap is the following time
between your vehicle and a vehicle
detected directly ahead in your path,
moving in the same direction. If no
vehicle is detected in your path, ACC works like regular cruise control. ACC
uses camera and radar sensors. See
Radio Frequency Statement
0393.
If a vehicle is detected in your path,
ACC can apply acceleration or limited,
moderate braking to maintain the
selected following gap. To disengage
ACC, apply the brake. If ACC is
controlling your vehicle speed when
the Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control
(ESC) system activates, the ACC may
automatically disengage. See Traction
Control/Electronic Stability Control
0 235. When road conditions allow
ACC to be safely used, the ACC can be
turned back on.
Disabling the TCS or StabiliTrak/ESC
system will disengage and prevent
engagement of ACC.
ACC can reduce the need for you to
frequently brake and accelerate,
especially when used on expressways,
freeways, and interstate highways.
When used on other roads, you may
need to take over the control of
braking or acceleration more often. ACC automatically slows the vehicle
down while navigating the curve and
may increase speed out of the curve,
but will not exceed the set speed.
{Warning
ACC has limited braking ability and
may not have time to slow the
vehicle down enough to avoid a
collision with another vehicle you
are following. This can occur when
vehicles suddenly slow or stop
ahead, or enter your lane. Also see
“Alerting the Driver”
in this section.
Complete attention is always
required while driving and you
should be ready to take action and
apply the brakes. See Defensive
Driving 0205.

Irregular Objects Affecting ACC
ACC may have difficulty detecting the
following objects:
.Vehicles with cargo extending from
the back end.
.Non-standard shaped vehicles, such
as vehicle transport, vehicles with a
side car fitted, or horse carriages.
.Objects that are close to the front of
your vehicle.
ACC Automatically Disengages
ACC may automatically disengage and
the driver will need to manually apply
the brakes to slow the vehicle when:
.The sensors are blocked.
.The Traction Control System (TCS)
or StabiliTrak/ESC system has
activated or been disabled.
.There is a fault in the system.
.The radar falsely reports blockage
when driving in a desert or remote
area with no other vehicles or
roadside objects. A DIC message
may display to indicate that ACC is
temporarily unavailable. The ACC indicator will turn white
when ACC is no longer active.
In some cases, when ACC is
temporarily unavailable, regular cruise
control may be used. See
“Switching
Between ACC and Regular Cruise
Control ”in this section. Always
consider driving conditions before
using either cruise control system.
Notification to Resume ACC
ACC will maintain a follow gap behind
a detected vehicle and slow your
vehicle to a stop behind that vehicle.
If the stopped vehicle ahead has
driven away and ACC has not
resumed, the vehicle ahead indicator
will flash as a reminder to check
traffic ahead before proceeding. In
addition, the left and right sides of the
Safety Alert Seat will pulse three
times, or three beeps will sound. See
”Alert Type ”and “Adaptive Cruise Go
Notifier” in“Collision/Detection
Systems” underVehicle Personalization
0 121. When the vehicle ahead drives away,
ACC resumes automatically if the stop
was brief. If necessary, press RES+ or
the accelerator pedal to resume ACC.
If stopped for more than two minutes
or if the driver door is opened and the
driver seat belt is unbuckled, the ACC
automatically applies the Electric
Parking Brake (EPB) to hold the
vehicle. The EPB status light will turn
on. See
Electric Parking Brake 0233.
To release the EPB, press the
accelerator pedal.
A DIC warning message may display
indicating to shift to P (Park) before
exiting the vehicle. See Vehicle
Messages 0120.
{Warning
If ACC has stopped the vehicle, and
if ACC is disengaged, turned off,
or canceled, the vehicle will no
longer be held at a stop. The vehicle
can move. When ACC is holding the
vehicle at a stop, always be
prepared to manually apply the
brakes.

256 DRIVING AND OPERATING
If a service message displays and the
above conditions do not exist, take the
vehicle to your dealer for repairs.
If the Park Assist System does not
activate due to a temporary condition,
a system off message is shown on the
display. This can occur under the
following conditions:
.The driver has disabled the system.
.An object is currently blocking the
rear sensors (for example, bike rack,
tailgate, trailer hitch, etc.). Once the
object is removed, Park Assist will
return to normal operation.
.The bumper is damaged. Take the
vehicle to your dealer for repairs.
.Other conditions, such as vibrations
from a jackhammer or the
compression of air brakes on a very
large truck, are affecting system
performance.
Automatic Parking
Assist (APA)
Automatic Parking Assist (APA)
with Braking
If equipped, under certain conditions
APA with Braking can use sensors
based on sonar technology along the
vehicle’s front, rear and sides to detect
a parking spot, and automatically park
the vehicle with some driver
assistance. The vehicle will
automatically maneuver into a
detected spot moving at or near idle
speed. It does this by automatically
steering and braking while the driver
is responsible for acceleration and
gear shifting as needed. The driver
must always be prepared to apply
braking or additional acceleration, as
needed. A display and audible beeps
help to guide the parking maneuvers.
{Warning
APA may not always detect objects
in the parking space, objects that
are not rigid (e.g. shrubs and
chain-link fences), objects below the(Continued)
Warning (Continued)
bumper, objects high off the ground
(e.g. flatbed trucks), hanging
objects, objects below ground level
(e.g. large potholes), or moving
objects (e.g. pedestrians, cyclists,
vehicles). Always verify that the
parking space is appropriate for
parking a vehicle. APA may not
respond to changes in the parking
space, such as movement of an
adjacent vehicle, or a person or
object entering the parking space.
APA does not detect or avoid traffic
that is behind or alongside of the
vehicle. Always be prepared to stop
the vehicle during the parking
maneuver.
How to Activate Automatic Parking
To activate APA, press the soft-touch
button or hard switch
Ofor the
system to begin searching for a
parking space while driving forward at
no greater than 30 km/h (18 mph). By
default, APA searches for parallel
parking spaces to the right of the
vehicle up to the sensors’ range of
